Cleaning methods for hot-dip galvanized steel strip generally include: alkaline washing, alkaline immersion, electrolytic cleaning, and hot water rinsing. These cleaning methods can control the total amount of residual oil and carbon on the surface of the galvanized steel strip to a very low level. Moreover, the surface of the galvanized steel strip is also ground during cleaning, which to a certain extent improves the adhesion of the steel strip surface. Therefore, cleaning hot-dip galvanized steel strip is essential.
